Verified July 29, 2026 · Author entity for usecos.app
Direct answer
usecos.app Research & Engineering is the public author identity for usecos.app calculator pages, methodology notes, validation reports, and source-backed data work. It is used because the site owner does not want a personal name displayed publicly.
Engineering scope
The work focuses on software and systems development: implementing calculator engines, documenting formulas, citing official sources, publishing validation cases, and adding regression tests that compare page examples against the calculation code.
Why usecos.app exists
usecos.app was built to make common Canadian finance calculations easier to inspect. Pages should show the formula, assumptions, source dates, limitations, and a practical calculator instead of asking users to trust an unexplained result.
Validation method
Calculator content is checked against source material such as CRA, CMHC, OSFI, Bank of Canada, Statistics Canada, provincial government pages, NHTSA, Transport Canada, and internal test cases where applicable. Validation reports publish downloadable scenarios when a result can be independently reproduced.
Credential limits
usecos.app Research & Engineering is not a mortgage broker, financial planner, accountant, lawyer, lender, insurer, mechanic, recall authority, or vehicle-history provider. usecos.app pages are educational calculator tools, not professional advice or official determinations.
